Space above content area

On the site I’m putting together (http://www.WCB.Norwhiz.com), I’ve figured out how to resize the main content area via CSS. I’m still having one issue that I’m hoping someone out there can identify. As you can see from this image http://i39.tinypic.com/dyan3a.png, there is a large gap between the embeded video and the nav menu. I’d like to shrink that gap just a bit, while still keeping the video below the logo’s bottom horizontal line.
